Title: Improvement in shaker conveyor
IPC: B65G27/00
Filed: 1947-08-08
Abstract: 647,495. Shaker conveyers. JOY MANUFACTURING CO. Aug. 8, 1947, Nos. 22064 and 22065. Convention dates, Aug. 25, 1944, and May 26, 1945. [Class 78 (i)] A shaker conveyer includes a trough 23, Fig. 2, drive means 15 to impart reciprocating movement to the trough, said drive means including a driven shaft 18 and actuating means 36 mechanically interconnecting the shaft and the trough, and mounting means 41 which is distinct from the drive means and relative to which the shaft is rotatable and which is for mounting the trough on the shaft for reciprocating movement. Drive. Figs. 2, 4, 5.-Motor 15 drives shaft 100 which drives crank arm 101 having spring drive mechanism 17, the movement of which rocks arm 20 and thus rocks rock-shaft 18 on which the arm is fixed, the whole being supported on base-plate 14. On rock-shaft 18 are fixed rocker arms 36 which therefore, through connecting arm 37 and lugs 38, drive the shaker trough 23. The latter runs on ball bearings (as in Fig. 5) on two supports; namely, ball frame 41 mounted on a collar 43 which is freely and statically supported by rock-shaft 18, and ball frame 48 fixed on base-plate 14. Ball frame 41 is adjustably anchored by bolt 102 and ball frame 48 is adjustably secured to the trough 23 by bolts 54 which may pass through any of a set of holes 52 arranged concentric with rock-shaft 18, so that the inclination of the trough can be varied. Angle drive (Figs. 8, 10).-The driving conveyer 19 drives the driven conyeyer 25 through rod 58 and square shaft 70. Rod 58 is slidably pivoted to conveyer 19, and shaft 70 is rotatably and axially fixed in bearings 72, and the rod and the shaft are connected by bevel gears 73-74 so that the reciprocating translating movement of conveyer 19 is converted into a reciprocating rotary movement of shaft 70. On shaft 70 is axially slidably mounted sleeve 60 which carries two members; namely, a pair of arms 76-77 fixed thereto and which drive the trough 25 through links 79-80, and a lower ball frame 103 which carries trough 25 by means of balls 82 and which is freely mounted on shaft 70 so that the trough may be tilted. Trough 25 is also pivoted at 84 to its upper ball frame 83 so that it can pivot in a horizontal plane. Feeding mechanism (Figs. 11, 12).-The reciprocating trough sections 26, 27, 28 are secured together at 93, have lateral feeding teeth 30, and are supported by brackets 92 from base-plates 85, the teeth edge resting upon the ground and the opposite back edge being formed with members 90 supported to run between ball-bearings 104 held in brackets 88-89 fixed on the base-plate. The feeding shovel therefore reciprocates and at the same time it may be urged forward into the coal by operation of handle 34 which is pivoted on fixed base-plate and works a pawl 33 in rack teeth 32 connected to base-plate 85.

The engine shown in Fig. 1 comprises compressor 1 and turbine 2 mounted on a common shaft 3, also a separate power turbine 4 mounted on a power output shaft which is disposed around an extension of the compressor-turbine shaft 3. The power turbine is drivingly connected to the drive shaft 6 through reduction gearing 5, one part 10 of a hydraulic coupling 9 being disposed in the gearing 5. The compressor-turbine shaft 3 may also be connected to the drive shaft 6 through reduction gearing 12 and the hydraulic coupling 9, the part 11 of the coupling being disposed in the gearing 12. A freewheel device 18 is provided to permit rotation of the gear wheel 17 when the gear wheel 15 is held stationary by the brake 16. The hydraulic coupling 9 is filled by means of fluid from pump 22 under control of valve member 20 which in turn is controlled by lever 19. Movement of the valve 20 in the other direction allows fluid to pass to the actuator 21 which controls operation of the brake 16. In Fig 2 the power turbine 4 is connected to the drive shaft 6 through reduction gearing 26. To allow the drive shaft 6 to be connected to the compressor-turbine assenbly a double hydraulic clutch 27 is provided, the two outer halves 28, 29 of the clutch being so connected in the reduction gearing 26 between the turbine 4 and the shaft 6 that they are driven at different speeds by that turbine. The two inner halves 30, 31 of the clutch are secured together and are driven through a gear stage 32 by the shaft 3 of the compressorturbine assembly. At part-load running, oil is supplied by pump 40 to the right-hand clutch 29, 31 by the way of the device 33; the compressor drive turbine 2 can now transmit power to the output shaft 6. For engine braking the valve 35 is operated whereby fluid passes from pump 40 to the left-hand clutch 28, 30. A governor 36 is connected to the shaft 3 to prevent racing of the compressor-turbine assembly by limiting the amount of fluid passed to the clutch 28, 30.

Abstract: 786,353. Colour television tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 25, 1955 [Aug. 10, 1954], No. 23156/54. Class 39(1). The phosphor screen of a C.R.T. is coated on the beam side with a series of electron permeable metal strips formed by sub-dividing a continuous layer of metal deposited on the screen. A monochrome screen, Fig. 2 (not shown) is made by depositing a layer of aluminium, magnesium or beryllium on the phosphor layer using an intermediate layer of nitro-cellulose which is afterwards dispersed, and dividing the layer by means of a reciprocating cutter. The strips are interconnected in two groups and potentials applied to the respective group to ensure interlaced scanning. For colour tubes, the phosphors are applied in lines by printing wheels either successively or simultaneously, the metal layer evaporated on and subdivided by a cutter as before. In Fig. 4, two plates 6 are placed together and coated with an adhesive e.g. phosphoric acid or sodium silicate. Three phosphor coated glass threads R, G, B, carrying red, green, and blue phosphors respectively and separated individually by glass threads 21 of slightly larger diameter are wound round the plates 6 from spools 17, 20, and the assembly is dried to set the adhesive. A conducting layer is evaporated onto both sides, and a light buffing or cutting action is applied to remove the coating over the spacer threads. The two plates are separated by cutting the wires and the individual conductors of the same colour phosphor are joined together. Alternatively the threads are laid across one or a series of plates in the same plane and secured by adhesive. The glass spacer threads may be replaced by threads of organic material dispersed by heat. In another modification, the phosphors are printed into straight grooves in a glass plate, metal evaporated on and the layer buffed to expose the glass ridges, Figs. 6-8 (not shown). In a further modification, Fig. 9, the grooves are laid down in a pattern with straight grooves 31, 32 for red and green and a zig-zag groove 33 for blue extending between the other sets of grooves as shown. The electrical connections between like metal strips may be tungsten wire helices extending over the strips and sealed to the glass plate at the sides ; short pins of chrome iron are sealed in the glass in positions occupied by the conductive lines and are afterwards connected together electrically. A screen may form the end wall of a C.R.T. being sealed in with glass frit or enamel or formed at its peripheral edge with a chrome iron ring which is seam welded to a similar ring on the conical portion of the tube. With a glass-glass seal, the mating edges are optically polished and the conductors are taken out at the sealed junction by using platinum paste strips burnt in the glass. The metal strips may be used to control and correct the scanning of the beam.
